French physicists developed a bubble that didn't burst for 465 days

French physicists have figured out a way to extend the usually short lives of bubbles.

University of Lille physicists published findings Tuesday in the journal Physical Review Fluids, recounting how they extended the "fragile and ephemeral" lifetime of a single bubble to a mind-blowing 465 days.

The typical bathtub or dish soap bubble lasts just moments before popping due to the "gravity-induced drainage and/or the evaporation of the liquid" inside the sphere, according to the study's authors.

But when researchers formed bubbles with a high concentration of glycerol — a compound commonly used in a host of foods and medicines — the compound was highly effective in staving off the sphere's inevitable death by pop. One bubble apparently lasted for 465 days.
